Implant Motion Analysis and CT-based Motion Analysis: Future and Applications

From CT images to measured motion

Mr Peyman Bakhshayesh connects the mathematics of CT registration with published hip, spine and pelvic research, a collaborator publication map, and future applications in ankle replacement and fracture healing.

The book explores how three-dimensional registration can compare objects over time or during carefully defined provocation. It explains translation, rotation, reference segments, measurement uncertainty and the difference between migration and inducible motion.

Inside the book

• The author’s research journey and the people behind the work
• Segmentation, registration, coordinate systems and precision
• Published evidence for implant migration and motion in the hip and spine
• Pelvic-fracture research and the interpretation of change over time
• Research proposals for painful ankle replacement and fracture healing
• External-frame removal, reconstruction planning and future validation
• A collaborator publication map and linked scientific references

Evidence and future applications

The ankle-replacement and frame-removal pathways are research proposals. The book distinguishes published evidence from investigational applications and does not treat 200 micrometres as a universal threshold for fracture union.

Motion measurements should be interpreted alongside symptoms, imaging, the measurement protocol and the clinical context. This professional educational monograph does not represent a patient-specific diagnosis or an endorsed clinical protocol.
